How to Migrate to Shopify Without Losing Your SEO
The pre-launch work that protects rankings during a Shopify migration: inventory, redirect map, content and launch day checks.
Most of the horror stories about Shopify migrations come down to the same thing: the new store launched, the old URLs disappeared, and nobody had a redirect map. Traffic that took years to earn went to 404 pages. The work that prevents this is not complicated, but almost all of it happens before launch day. Here's the sequence that keeps your rankings intact.
Start with a full inventory of what you have

You cannot protect pages you haven't listed. Before anything else, export a complete picture of the current site:
Every URL, from a crawl of the site rather than from memory
Your top pages by organic traffic and by revenue, from analytics and Search Console
Your current titles, meta descriptions, and H1s
Pages with backlinks pointing at them, since those are the ones that hurt most if they break
Product and collection pages, blog posts, policy pages, and any landing pages built for campaigns
Current rankings for your main terms, so you have a baseline to compare against
Keep this in a spreadsheet. It becomes your redirect map, your QA checklist, and your evidence if something goes wrong later.
Understand how Shopify URLs are structured
Shopify uses fixed paths, and you need to plan around them rather than fight them. Products live at /products/handle, collections at /collections/handle, blog posts at /blogs/blog-handle/post-handle, and pages at /pages/handle.
That means URL patterns from WooCommerce, Magento, or a custom build will almost never carry across unchanged. Decide early which handles you'll use, keep them close to the old ones where it makes sense, and avoid the temptation to redesign your URL structure and your platform in the same move.
Build the redirect map before you launch
Every old URL needs a destination, and the destination should be the closest equivalent page, not the homepage. Redirecting everything to the homepage is the most common mistake in migrations, and it wastes most of the value you're trying to keep.

A few rules that keep the map sane:
Product to the same product. Collection to the same collection. Post to the same post.
If a product no longer exists, send it to the closest collection, not to a dead page.
Avoid chains. Old A to new B is fine. A to B to C loses time and clarity.
Include the variations: trailing slashes, uppercase, and any parameter versions that were being indexed.
Don't forget pages people reach from printed material, email footers, or QR codes.
Importing redirects into Shopify
Shopify lets you import redirects in bulk rather than entering thousands by hand. You create them under Content, then Menus, and the URL redirects list has an import option with a sample CSV template. Shopify's documentation says "URL redirects start working immediately" once created.
Two limits worth knowing. Shopify's documentation states "You can create a maximum of 100,000 URL redirects" on standard plans, with a much higher ceiling on Plus. And some URLs can't be used as redirect sources, since "You can redirect only from broken URLs," so a path that still resolves to a live page on your new store won't redirect.
Move the content, not just the products
Product data usually gets migrated carefully because it's the obvious part. Content gets forgotten, and content is often what ranks.
Blog posts, including their publication dates and authors
Buying guides and category descriptions, which frequently exist on old platforms as custom fields
Reviews, which need a proper export and import rather than a fresh start
Images, with their alt text intact
Internal links inside content, updated to point at the new URLs rather than through redirects
Where old category pages had long descriptions that earned rankings, recreate them. On Shopify that may mean a theme section or a collection metafield rather than the default description field.
Keep your on-page SEO intact
Titles and meta descriptions do not migrate automatically from most platforms. Export them, then set them on the new store through the search engine listing fields, or with a bulk editor if you have hundreds. Check that your new theme outputs one H1 per page and that it's the product or collection title rather than a logo.
Also check canonical tags and structured data on the new store before launch, since themes vary. A theme that outputs no product markup, or two conflicting sets of it, is worth catching before Google sees it.
Launch day checklist
Remove any password protection and confirm the store is reachable.
Check robots.txt and confirm you are not blocking the site.
Submit the new sitemap in Google Search Console. Shopify generates sitemap.xml automatically.
Test a sample of redirects from your map, including the top twenty pages by traffic.
Verify analytics and conversion tracking are firing on the new store.
Check that the domain, including the www or non-www version you use, resolves correctly and consistently.
Place a real test order end to end.
What to expect afterwards, and what to watch
Some movement in rankings after a migration is normal while search engines recrawl and reprocess the site. What you're watching for is whether it settles. Check Search Console a few times a week for the first month:
Coverage and indexing reports, for a spike in 404s or newly excluded pages
The performance report, filtered to your most important pages rather than site totals
Crawl stats, to confirm the new URLs are being fetched
Your server logs or redirect reports, for old URLs still being requested that you missed
Keep your redirects in place permanently. There's no point at which removing them becomes a good idea, and the cost of keeping them is zero.
The mistakes that cause real damage
If you only remember a few things from this, make it these: don't redirect everything to the homepage, don't change your URL structure and your platform at the same time without a map, don't launch with the site still blocked from crawling, and don't delete the old site until you're certain the redirects cover everything. The old platform's hosting for one more month is cheap insurance.
Migrations are one of those projects where the preparation is most of the work, and the launch is anticlimactic when it's done well. If you want someone to own the redirect map and the technical checks while your team focuses on the catalog, that's part of what we do in our Ecommerce SEO service.
